Digital preservation of micro-gestures in the making process of Indonesian iconic traditional rattan chair using immersive 360° learning videos and photogrammetry

Although rattan artifacts have been extensively archived, limited studies have focused on documenting the knowledge and craftsmanship skills of artisans preparing traditional rattan chairs. These skills involve tacit knowledge, which is often very difficult to capture and transfer. This study aimed to preserve the creation process of iconic Cirebon rattan chairs (Papasan, Bahama, Kelek, Gentong, and Keong), which have been produced for over 50 years, through the use of digitization. By combining 360° video technology and photogrammetric techniques, the study created immersive learning videos that captured artisans' subtle and difficult-to-observe micro-gestures. The 360° video technology recorded the micro-gestures of artisans, and photogrammetry provided realistic three-dimensional visualizations of the furniture and tools used. Testing through visual recall demonstrated that the 360° learning videos could effectively teach delicate and subtle micro-gestures, such as the use of the chest, knees, armpits, soles, and toes, unique to rattan chair making.
